When we first heard rumors about Apple’s adapters to allow owners of already-released iPhone accessories to continue using them with the iPhone 5 and its new Lightning connector, they were supposed to both be priced around $10, as well as be an Apple exclusive. We’ve already learned that the first point there was off, and Apple’s instead charging more like $30 for these accessories. Luckily, it turns out the second point was wrong as well, and third-party accessory manufacturers are already preparing some much more affordable adapters.

Amazon lists products from a few companies, and it looks like they’re starting all the way down at the $10 point we were hoping for. The only thing that’s not clear is just how compatible these may be; we know that Apple’s official adapter doesn’t support video-out or iPod controls, but still handles analog audio-out. With these new guys, it’s not clear if that audio is still supported, or if they’re purely for USB data and charging purposes.

Still, $10 is a deal compared to what Apple wants, so even if these don’t fully deliver, they might be worth picking up, if only as spares.
